The true statement among the options provided is:
**The human body uses 20 amino acids to form all types of proteins.**
This is correct because there are 20 standard amino acids that cells use to synthesize proteins. The other statements are incorrect for the following reasons:
1. Amino acids must be assembled in a specific order to form functional proteins, as the sequence determines the protein's structure and function.
2. tRNA (transfer RNA) is not attached to specific proteins; instead, it carries specific amino acids to the ribosome during protein synthesis, where it matches the codons on the mRNA.
3. Amino acids form a polypeptide chain via peptide bonds, which are covalent bonds formed between the amino group of one amino acid and the carboxyl group of another, not carbon-carbon bonds.
